Study On The Treatment Effect Of Labial Pronunciation Training On Dysarthria After Stroke

Objective:This study aims to explore the treatment effect of labial pronunciation training on the basis of conventional speech language therapy on dysarthria after stroke. Meanwhile to study the clinical characteristics and training methods of articulation disorder.Methods:Select 20 patients with the diagnosis of dysarthria after stroke,who entered the Department of rehabilitation medicine in huadong hospital in 2015-2016. The patients were randomly divided into experimental group and control group through random number generated with Excel random function, 10 patients for each group. The control group was treated with conventional speech language therapy, while the experimental group was treated with labial pronunciation training on the basis of conventional speech language therapy. Two groups of treatment were 30min/ time,while the experimental group was treated with conventional speech language therapy for 20 min/ time and labial pronunciation training for 10 min/ time. Two groups were treated 5 times / week, a total of 4 weeks. Therapist carried on one to one training in a quiet and stable environment. Basic life indication was determined before and after treatment; the modified Frenchay articulation disorder rating scale and the articulation organ examination were used. Observe the score of the modified Frenchay articulation disorder rating scale, the number of “a” items, articulation function and the curative effect index to evaluate articulating function; the mini-mental state examination was used to measure recognition function. Using spss19.0 for statistical analysis of the data, Measurement data were expressed by ± s, The measurement data are compared with the normal distribution using t test, Comparison inside group used paired t-test,comparison between groups used independent sample t test. If it didn’t conform to the normal distribution, the rank sum test was used. Fisher exact probability in the Comparison of count data. Rank sum test was used to rank data. All significance levels were set at p<0.05.Results:1.The temperature, pulse, respiration and blood pressure of the two groups were all in normal range before and after treatment, and there was no significant difference between the two groups(p>0.05).2.After treatment, there was an decrease in the score of the modified Frenchay articulation disorder rating scale compared with that before treatment, and the difference was statistically significant(p<0.01). Compared with the control group, the score of the modified Frenchay articulation disorder rating scale of the experimental group was lower, and the difference was statistically significant(p<0.01).3.After treatment, there was an increase in the number of “a” items of the experimental group compared with before treatment, and the difference was statistically significant(p<0.01), there was an increase in the number of “a” items of the control group compared with before treatment, and there was no significant difference(p>0.05).Compared with the control group, the number of “a” items of the experimental group was higher, and the difference was statistically significant(p<0.05).4.After treatment, the experimental group compared with before, the reflex function,the lip movement, the throat movement scores were decreased, and the difference is highly significant(p<0.01). Respiratory function, mandibular movement, movement of the soft palate, tongue movement, verbal expression scores were decreased, and the difference was statistically significant(p< 0.05), The control group compared with before, Throat movement, tongue movement and speech expression scores were decreased, and the difference was highly significant(p<0.01). the reflection function,respiratory function, and the lip movement score were significantly decreased, and the difference was statistical significant(p<0.05), The movement of mandible and soft palate movement function score were decreased compared with before, but the difference was not significant(p>0.05); Compared with the control group, the score of the respiratory function and lip movement of the experimental group, with statistical difference(p<0.05), Other articulation function scores were lower without statistically significant(p>0.05).5.Compared with the control group, the total effective rate of the experimental group was higher, and the difference was statistically significant(p<0.05).6.After treatment, the experimental group and the control group were compared with before, MMSE scores were increased, the difference was highly significant(p<0.01),but there was no statistical difference between the two groups(p>0.05).Conclusion1.Labial pronunciation training can help improve the articulation function after stroke.2.Labial pronunciation training is safe and effective for dysarthria after stroke.3.There may be some relationship between the improvement of articulation function and the improvement of cognitive function.
